Brushless DC Motor Speed Driver BLDC-5015A Features
- SPWM, Speed/Current alike close loop technology, smooth rotation
- Smooth torque output within speed range (8000 rpm Max.)
- 1:75 Max. speed regulation ratio
- 60°/300°/120°/240°Electrical angle adjustable
- Speed regulation: potentiometer adjust / Analog input
- Run/Step, Quick Brake, CW/CCW rotation shift
- Speed output, Alarm output(O.C.)
- Over current, over voltage, stall, missing speed Alarm
24～50VDC, Capacity:up to motors
Rated 15A, Peak 45A(≤3s)
Keep away from oil, dust, and acid gas
Voltage: 24～50DC, normally Linear Power Supply applied(appendix),
ripple voltage higher than 50V may damage driver. The output
current of LPS shall be 60％more than that of driver. In case of
switching power supply(strongly recommended)applied, please pay
attention to the current shall meet motor’s current.
Attention: incorrect connection may cause driver damaged.
- Speed regulation choice(RV ; AVI)
1.Setup speed by potentiometer (RV).The dipswitch SW2 must be ON
status to enable this function. CW rotate the potentiometer will
increase speed. CCW- speed down.
2.Setup speed by analog input (AVI). The dipswitch SW2 must be OFF
status to enable this function..AVI terminal accept 0～5V voltage or
PWM signal from controller.AVI terminal with input resistance of
100K, current consumption≤5mA.
CW—speed up, CCW—speed down
0～5V analog input
1KHz duty cycle
Only one of above two modes can be used to adjust speed (another
mode shall be enabled). Once AVI terminal applied, (RV)
potentiometer shall be CCW turned to Min. position.PWM signal are
5V TTL level.
ENBL terminal is applied to control motor Run/Stop, Common positive
terminal is ＋5V.
Optical coupler short circuit make motor run, it open circuit make
See below circuit
F/R terminal is applied to shift motor rotate direction, common
positive terminal is＋5V.
Motor run in CCW when optical coupler is short circuit, motor run
in CW when optical coupler is open circuit.
Attention:don’t change the connection sequence of phase wires of
motor to shift rotate direction.
BRK terminal applied to stop rotation quickly. Motor will stop
normally within 50ms. But inertia of load can’t exceed 2 times of
motor inertia, otherwise brake will cause driver alarm.
Time of acceleration and deceleration must be put into controller
in case of too big load inertia,
And please don’t use brake function in such condition.
The optical coupler short circuit will brake motor, optical coupler
open circuit release motor to run.
- Setup different electrical angle
Dipswitch SW1 can be setup to fit motors with different electrical
120°or 240°hall signal, they are in opposite rotation direction
60°or 300°hall signal, they are in opposite rotation direction
- Motor rotation speed output(SPEED)
Pulse generated by driver are proportioned with motor speed,
(isolated O.C. output) it can be increased to be a random level. 6
multiple frequency processed output.
Motor speed＝60×SPEED(pulse freq.)/pulses per rev. of
motor；p.p.r＝motor pole pairs×6
Driver will enter protection mode and stop motor running in case of
OVER CURRENT, OVER VOLTAGE, SHORT CIUCUIT, MOTOR STALL arise, LED
on driver will be light, and ALM signal will be available. Please
cut off driver’s power supply, check wiring and voltage. High
voltage is not permitted for big inertia motor, as it may cause
run/stop frequently and over voltage alarm. Circuit of this
function refer to pic. 2.
